I have noticed a possible error in php permissions.
Pathway: ACP > Permissions > Group Permission in forums > Registered Users > select All Forums > Message > Can delete your own messages > YES.
I have this function active for the forum in verion phpBB 3.2, after update to 3.2.1 this function stop to work and all registred users can not more delele your own message now.
